The damping force on an oscillator is directly proportional to the velocity. The unit of the constant of proportionality is

View answer and explanation

Correct option: C

\mathrm{kgs}^{-1}

Option C (

\mathrm{kgs}^{-1}

) is correct because the damping force is proportional to velocity (F = bv), so the constant of proportionality (b) has units of force/velocity.
